MIIS (Meditech Interpretive Information System)

MIIS (Meditech Interpretive Information System) is a MUMPS-like programming language developed by Meditech in the 1970s. Early development of MUMPS is credited to A. Neil Pappalardo and Octo Barnett of Massachusetts General Hospital. MUMPS evolution took two major directions: MUMPS proper and MIIS. MUMPS became an ANSI and ISO-standard language. When many MUMPS implementations standardized to be compatible, MIIS did not standardize, but became a proprietary system instead.
